hey guys. I heard about PCSX2 and I became really excited to use this amazing software. I actually just spend $225 upgrading my PC just so I can run this emulator, but I'm having some trouble, everything it still pretty choppy, but at least it doesn't crash when I try to start a game now.

Yes, as everyone else said, your CPU slows you down the most. Would recommend getting a "real" dual core such as E8400.
Some games might run just fine on this set though. So what game(s) are you trying to play Sheaty?
